    • Great for computer speakers or amateur music/video production
Size: 3.5" Gen 2 Color: White
Review Image by BUSKER BUSKER
The media could not be loaded. When my Creative Pebble 2.0 computer speakers stopped working, I knew I needed a new set of speakers. In years past, I had the Rokit 5 G2 monitors and matching subwoofer for my main video editing computer. But right now I don't have that kind of money to spend, and I'm not currently doing enough paid editing work to justify that kind of investment. I needed speakers that would mostly be used for listening to music, watching video content, and for editing videos occasionally. Enter the PreSonus Eris 3.5, which at just under $100 was at the top end of what I could spend. I almost went with the Ortizan C7, but decided on these instead both for the smooth volume knob adjustment and the PreSonus brand name. They were easy to set up with my MacMini, they look great on my white desk, and there's always the option to get the Eris subwoofer if I want to. I did not need Bluetooth connectivity, just wired RCA or 3.5mm, with the option to do 1/4" later on. Be aware these are not true active monitors, they're basically something between that and computer speakers. The left side has the power cable, the inputs, and the bass/treble adjustments. The right speaker is a passive "satellite" that connects with regular speaker wire. At 25w each, I can't see the point of upgrading the wire to a larger gauge. The tweeters do have a grille covering them which is nice, and the carbon fiber woofers have a smooth concave dustcap. I'm not worried about denting the woofer or tweeter. Now let's talk about sound. These definitely get loud enough for a bedroom or small office. I rarely turn mine up past 50% and at that level it's louder than I normally listen to things. The response is maybe a little heavy on bass/mid-bass, so I turned down the bass knob on the speaker to about 30% and use an EQ program on my computer to slightly boost the mids/highs and roll off the bass. With that, the speakers sound balanced to my ears. If you're using these for consuming entertainment, they certainly fit the bill. If you're mixing your own music/videos as an amateur or low-budget prosumer, then these will probably work if you set the EQ right for your room. I would still recommend checking your mix on a good pair of headphones and also a cheap mono speaker. They look good, they sound good, and have just enough upgrade options to work at the prosumer level. I did not pay extra for the Bluetooth feature as I figured the subwoofer comes with that functionality if I really want it later on. EDIT: I bought a right angled power cable and angled RCA adapters so that I could fit the Left speaker closer to the wall than the factory cables would allow. ... show more

    • Amazing! Best speakers on the Market!
Size: 3.5" Gen 2 Color: Black
Well worth the price, probably the best pc speakers on the market. I’ve had them for about 7-8 months now with no problems! Easy to setup though it looks a bit intimidating compared to other speakers. Quality is clear and it’s very loud! I will note that when you first turn your pc on or start using the speakers after a while they do take about 5-10 seconds to kick on. I just call it the “warming up” phase. Again it’s quick and not that big of a deal and the quality makes up for the few second inconvenience! I can’t speak to the Bluetooth as I got the wired but if you are considering the wired version I’d go for it! ... show more

    • WOW!!
Size: 3.5" Gen 2 Color: Black
I bought these for use with my gaming PC. My old set died and while I'd never really put much thought into PC speakers before, I decided to try something different this time. When I first connected these, I was impressed by the volume but sound quality could have been better, particularly in the bass. I did two things to fix this: I got a high quality external DAC for my PC and I added the matching PreSonus subwoofer. WOW!!!! THE DIFFERENCE IT MADE!!! It turns out that the cheap DAC I was using before was adding a lot of electrical noise to the signal and, in addition to that, these speakers/cables were picking up a ton of RF noise from the nearby wifi router and the PC itself. Further, while these speakers are great, they just aren't made to have amazing bass on their own and so obviously the matching sub solved that problem. These speakers are made to accept balanced cable connections, which I didn't know anything about, but I did the homework and bought some balanced cables and the difference is night-and-day better compared to the standard RCA breakout cable that comes with the speakers. So, these speakers are a home run but if you're going to invest in them, I recommend making sure they can live up to their potential by connecting them to quality equipment with good cables, and by also getting the sub if you can manage it. ... show more

    • Big bang, little buck
Size: 3.5" Gen 2 Color: White
These are very nice performing little monitors that are perfect for a small desk setup. They give good representation of a mix and are invaluable when paired with monitors that reveal the lower frequencies. The sound quality is very nice but they, being small, don't throw the bass out like you may want. I purchased their larger counterparts (Eris series) but still find these little desktop monitors very useful and they sound fantastic as PC speakers. Also, I've found, it's good to mix using some "great" speakers and then check it out on speakers that mirror what most people listen on. Overall, very clear, very solid, very easy to setup. For the cash? Most recommendable. ... show more

    • Amazing for my audio setup!
Size: 3.5" Gen 2 Color: Black
The PreSonus Eris 3.5 Studio Monitors are a compact yet powerful pair of near-field reference speakers that deliver clear, balanced audio perfect for home studios, content creation, or desktop listening. With a 3.5″ woven-composite woofer and 1″ silk-dome tweeter, they produce detailed lows and crisp highs across a wide 80 Hz–20 kHz range, and the built-in 50 W of Class AB amplification gives them more punch than you’d expect for the size. Adjustable high- and low-frequency controls and versatile input options (balanced TRS, RCA, and ⅛″ aux) make it easy to tailor the sound to your space and gear. Overall, they’re a reliable and affordable option for anyone wanting genuine studio-style monitoring or high-fidelity playback in a small footprint. ... show more
